I am not sure that cars or vans are excluded i.e a well equipped camper van could have everything that a small site hut has. The main point is that if a risk assessment identifies extreme cold as a potential risk to health and safety, suitable remedial action is required. I would imagine that an unheated hut (or car) wouldn't be satisfactory. Also a car is rarely an adequate substitute for a lavatory (although no doubt someone has a 'tale' to tell!!).
